1. Combustion of methane.
CH4 + 2O2 = CO2 + 2H2O.
2. Obtaining calcium carbonate.
CO2 + Ca (OH) 2 = CaCO3 + H2O.
3. Thermal decomposition reaction:
CaCO3 = CaO + CO2.
4. Formation of carbonic acid when carbon dioxide dissolves in water.
CO2 + H2O = H2CO3.
5. The decomposition reaction is reversible to acid formation.
H2CO3 = CO2 + H2O.
